mainvalve is closed; and the invention 0011- sists in certain novel constructions and com binations of parts as will be hereinafter de= scribed and claimed. In the drawing, Figure 1 is a vertical longitudinal section of the lower portion of a hydrant embodying our invention. Fig; 2 is a cross section on about line 22 of Fig. 1. Fig. 3 is a longitudinal section of the upper portion of the hydrant, and Fig, 4-. is an enlarged detail view of the drip valve lever, and the parts with which it cooperates. By our invention we seek to provide a simple, durable, inexpensive and eflectivc waste drip mechanism, all of the parts of which may be removed through the frost case. In the construction shown, the frost case A fits at its lower end within the upwardly projecting flange B on the base elbow B; such frost case and flange B are provided with orifices a and I) through which the waste discharged from the barrel C may pass. The barrel C fits within the frost case A at its upper end, as shown in Fig. 3, and at its lower end as shown in Fig. 1. The elbow B is provided at the base of the flange 3 with the inwardly projecting horizontal annular flange B receiving on its upper edge a packing B and threaded on its inner edge to receive the lower end of the valve chamber as presently described.

The valve chamber D has a cylindrical body portion D, is provided at its upper end with the outwardly projecting top flange D bolted at D to the flange C on the lower end of the barrel, and the lower end of the cylindrical body D has a projecting threaded nipple D which screws into the provided the outwardly projecting annular flange D which bears upon the packing B and secures a tight joint between the parts B and D at the lower end of the latter, as shown in Fig. 1. The interior of the body D at its lower end is formed at D into a valve seat for the main valve E which is fitted to said seat and is secured to the lower end of the main valve stem F, which latter may be suitably operated in a longitudinal direction by any well known means to open and close the main valve E, as will be understood by those skilled in the art.

By the described construction, it Will be noticed we form the valve chamber separate from the barrel and the elbow, and make it detachable from the latter and to form a connection between the lower or base elbow and the barrel, and this valve chamber may be made of any suitable metal, and can be readily withdrawn through the frost case for repairs or for other desired purposes.

The valve chamber D is provided at one side with a valve seat G, preferably of bronze, opening into the space within the frost case, so the waste discharged through the valve seat G may pass out of the openings a b, and the seat G as shown is preferably provided with a separate tube inserted in the side of the chamber D and projecting within said chamber in position to receive the drip valve H which is carried on a rocking lever H arranged for operation as presently described.

For supporting the drip lever I-I,'we provide the valve chamber D with an arch 1,

extending from side to side of the valve chamber at the upper end of the latter, provided centrally with a box or hub I, to receive the main valve stem F, and slotted radially at I on one side of the hub to receive the drip valve lever H, which is pivoted midway between its ends at H within the slot I as shown in Figs. 1 and 2 of the drawing. This drip valve lever extends alongside the main valve stem F, and is provided on its side adjacent to said stem with inwardly projecting portions h and h, respectively, above and below the pivot H of the valve lever H. These projections h and it are preferably inclined as shown in Fig. 1, and are arranged for engagement by the shoulders f and f, on the valve stem, such shoulders f and f being preferably the upper and lower ends of a plate f secured to the side of the stem F and op erating therewith through the hub I of the arch I and arranged above and below the said hub to operate upon their respective projections on the drip valve lever. By having the arch slotted to receive the drip valve, the height of the arch is reduced, thereby increasing the waterway. It is manifest that by pivoting the drip valve lever to the arch we are able to arrange the said lever partly below and partly above the arch thus reducing the height of the arch as compared to a construction in which the lever is supported and arranged entirely below the arch. It will also be noticed by the construction of the central hub I with a hole through which the main valve stem passes, and of a shape corresponding to the said main valve stem, together with the plate f and preferably in the form of an oblong square, we provide for operating the drip valve, and at the same time prevent the parts from being put together in any way but the correct one.

The drip valve H is preferably recessed and fitted with packing H held in place by a screw or rivet H and fitted to the valve seat G, as will be understood from the drawing.

In operation it will be noticed that when the main valve stem is moved upward to close the main valve E, the shoulder f engaging with the projection lz, on the drip valve lever will operate the same to the position shown in Fig. 1, and as the main valve E is closed, the waste or drip valve will be opened so that the barrel may be drained as desired. On the other hand, as the valve stem F is lowered to open the valve E, the lower shoulder f engaging the lower projection h of the drip valve lever will close the drip valve H against its seat G, and thus shut olf the passage of waste through the drip valve when the main valve is open. This operation, it will be noticed, is positive in both the opening and closing of the main valve, and is elfected in a simple manner and by a mechanism which possesses no parts likely to get out of order.

e claim:

1. The combination substantially as here in described, of a base elbow, a main valve chamber threaded at its lower end into connection with the base elbow and provided with a lateral flange overlying the base elbow, and with packing between the said flange and elbow, and also having at its upper end an external lateral flange and provided internally with a cross arch having a central hub having an opening for the valve stem and slotted radially on one side of the hub for a drip valve lever, the said valve chamber being provided below the said arch with a lateral waste opening, a
